Answer:
0.10
Step-by-step explanation:
14 red block
9 blue blocks
10 purple blocks
25 green blocks
12 yellow blocks
18 orange blocks
----------------------------
88 total number of blocks
9 blue blocks
p(blue) = 9/88 = 0.10
The quadratic formula is =(-b+-sqrt(b^2-4ac))/2a
as you notice the term under the square root is b^2-4ac if it is postive then the equation clearly will have two real soultions if it is negative then the equation will have two imaginary soultion if it is zero then the the equation will have one soultion
so let us calculate b^2-4ac for our given equation
x^2=4x-5 so let us write it in general form which is ax^2+bx+c=0
subtracting 4x from both sides
x^2-4x=-5
adding 5 to both sides
x^2-4x+5=0
a=1,b=-4,c=5
b^2-4ac=(-4)^2-4(1)(5)=16-20=-4
which means the equation has two imaginary soultions

It is the second answer:
8x²/y -2 is a solution which is equivalent to (8x²-2y)/2. Proof:
Reduce 8x²/y -2 to the same denominator:
8x²/y - 2y/y = (8x² - 2y)/y
